First Let me start by saying this guide might not be perfect but will be good.
I don't flash 100 BlackBerry's a month or even 100 at all but this is to help those who are lost or having trouble getting there BlackBerry Flashed to metro.

Things you will need:
CDMA Workshop:
I think its offered on this site or just google it.

BlackBerry Desktop Manger:
[Only registered and activated users can see links. ] would sugest using 5.0.1 because sometimes I myself wont see a phone on 6.0

Metro Pcs PRL: 3022
[Only registered and activated users can see links. ]

I will be going by section starting with:
Flashing the phone
adding web

How to Flash the BB 8530 to metro PCS:
1. Open BlackBerry Desktop Manager
2. Plug the phone into the PC
3. Make sure all drivers are installed of there is no SD card it will fail that install its ok!
4.Open CW (CDMA Workshop)

Adding Web:
Make sure the phone is back on and connected to blackberry desktop manager.
1. On the phone go to Options>Advance Options> Service Books
2. Put the phone in Legacy Mode
How to: Press and hold Alt on the phone Press SBEB
3. Go to Desktop Manger and Click Advance
